简便计算:99.99*22.22+33.33*33.34
简便计算:99.99*22.22+33.33*33.34
简便计算:99.99*22.22+33.33*33.34
99.99×22.22+33.33×33.34
原式=(33.33×3)×22.22+33.33×33.34
=33.33×66.66+33.33×33.34
=33.33×(66.66+33.34)
=33.33×100
=3333
3331.0002
99.99*22.22+33.33*33.34
=33.33*3*22.22+33.33*33.34
=33.33(66.66+33.34)
=33.33*100
=3333
99.99*22.22+33.33*33.34
=33.33*3*22.22+33.33*33.34
=33.33(66.66+33.34)
=33.33*100
=3333
楼上不要抄袭 我打字慢了一点而已 楼主选我把 please
主要考的知识是提取公因数,应该在初中才学的内容啊,怎么现在的小学就有了 过程:99.99*22.22+33.33*33.34
=33.33*3*22.22+33.33*33.34
=33.33(66.66+33.34)
=33.33*100
=3333
